DROP_VLAN_MASK_TO_NULL

[davidtrabanco]

Hi Community,

I have a UCS Servers with Fabric Interconnect and I'm doing troubleshooting because I see CRC errors on several IOM ports, I ran the command # show platform fwm info asic-errors 0 to determinate the cause of those errors, in the field DROP_VLAN_MASK_TO_NULL I see a high value but I couldn't find what it refers to, I would appreciate if someone can explain the meaning plese.

# show platform fwm info asic-errors 1
Printing non zero Carmel error registers at slot 0 asic 1

You don’t say which version of IOM or firmware you are running, but I have been tracking 4.2(3h)  - which was released today - which addresses bug CSCwe98053 : CRC errors are seen in a setup equipped with Cisco UCS 2408 IOM connected to Cisco UCS B-Series server HIF ports.

Link to the release notes fixed caveats: https://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/release/notes/cisco-ucs-manager-rn-4-2.html#resolvedcaveats4.2.3h

Hi riaan.vanniekerk,

Thank for replay, below the information:

PID:UCS-IOM-2204XP

Running Version:4.1(3e)

As you can see, it's different model and version of IOM.
